BACKGROUND OF THE INVENTION For example, DE 41 41 382 A1 describes a wireless feature-enhancing telephone with additional functions such as a computer, recording device, remote control and broadcast and / or television receiver. Components that provide telephone functions such as number keys, function keys, and obvious power supply should be shared by the phone and the building's additional functions. , Other parts of the mobile communication device such as buttons, display and power supply < sharing in the mobile communication device was not successful, because the mobile communication device needs to be fully available when it is not in use. The object of the present invention is to share circuit elements of a mobile communication terminal for receiving broadcast signals. This purpose is achieved by receiving broadcast signals with at least the component in the receiving area, so as to cover the gap between the reception of the broadcast when receiving the mobile communication control information. Its advantages: The mobile radiotelephone receiver element can now also be used for broadcast reception 'without the gap found by the listener when receiving control information. It is clear that when the digital signal processor covers the gap of the broadcast signal, the extra space required for the broadcast reception is less than when the broadcast reception area receiver area is integrated next to each other.

A Fig. 2 shows a first embodiment in which only predetermined receiving stage circuit elements are shared by mobile radio reception and broadcast reception. Fig. 3 shows a second embodiment in which the integrated receiving stage is completely used. For receiving mobile radio signals and broadcast signals. Figure 1 shows the basic concept of a receiver according to the invention. As far as possible, the components of the receiving area 1 are shared by the receiving mobile radio channel and the radio station, and further processing is performed at the audio level 2, and a digital signal processor 3 is reproduced via a speaker 4 or headphones. When receiving a broadcast, the control device 5 switches the reception area to receive a control channel for receiving the mobile radio frequency band at a specified time. At this time, the digital signal processor 3 generates a substitute signal to cover the broadcast band receiving gap achieved by receiving the control information. For example, here, the digital signal processor only repeats a series that the broadcast band receives before the switching, such as the last 20 ms audio signal received. Fig. 2 shows a possible embodiment of a GSM, DCS 1800 and broadcast signal reception zone 1 of a multi-band radio in a VHF band. Most of the components in the receiving area are contained in an integrated circuit 1C. Since the broadcast receiver does not use the transmission portion ', it is not a part of the present invention and is omitted for clarity. Other components familiar to the skilled person, such as the keyboard, display element and power supply, are well-known for mobile radio reception and broadcast reception, so they are omitted. A first antenna 6 and a first pre-filter 7 are used to receive the dcs 1 800 band, while a second antenna 8 and a second pre-filter 9 are used to receive the GS M band, and a The third antenna 10 and a third pre-filter-5- This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm)

The individual received signals are supplied to separate mixing stages 15, 16, 17 through different pre-amplified ports 12, 13, and 14. However, the W-wide-band rate is generated in a single oscillator 18, which uses a P L · L · circuit and is shared by all mixing stages, that is, all frequency bands. The circuit of this embodiment includes a quartz oscillator! 9 (a and the integrated circuit) c external quartz crystal 20)-automatic frequency control unit 21, a lock detector 22, a sequence switching element 23, a pre-counter 24, a programmable counter 25, a The phase detector 26, a charging electric pump 27, a displacement register 28, a station 1 memory 29, and a low-pass filter 3 external to the IC. The receiving concept selected in this embodiment is a near-zero intermediate frequency concept, and a low intermediate frequency such as 100 kHz is used to compare with the receiving frequency. Each received frequency band is supplied to a first-automatic gain control 31, and then to a polyphase near-zero IF filter 32. Then the GSM and DCS 1800 received signals are processed by the second automatic gain controller 33, a buffer amplifier 34 and an analog to digital converter 35, and a third automatic gain controller 37 and a multi-phase The parallel processing branch of the FM detector 38 provides the broadcast signal. According to the concept of the present invention, it is necessary to find a compromise between receiving the individual circuit elements of the receiving area shared by the mobile radio band and the broadcasting band, and the cost of the circuit elements. The implementation of the above = the PLL circuit has increased the cost. Because the frequency of the broadcast transmitter is more unstable than that of the mobile radio transmitter, the reception frequency must be readjusted due to the change in the transmission frequency of the broadcast transmitter. However, in this second embodiment, an integrated circuit (a Philips circuit OM5178 in this embodiment) is completely used without improvement, even if the broadcast signal frequency band is -6-

Description of the invention (The same is true for reception. This is because the receiving frequency of the mobile radio frequency band and the broadcasting band are different. Therefore, the PLL needs a lower reference clock. According to the concept of the present invention, the GSM receiving signal and the broadcasting receiving signal pass through separate antenna , 42 and the pre-separation filters 41 and 43 are received to supply the high-frequency signal input of the integrated circuit 丨 c through a first switch 45 and a first symmetric and asymmetric converter 46. In addition, the The GSM frequency band and the broadcast band have separate externally controllable oscillators 4 7, 4 8 and receive an individual control signal included in the child product circuit via an external p LL filter 4 9! C p LL switching circuit. This correlation can be The output signal of the control oscillator is selected by a second switch 50 and supplied to the integrated circuit by a second symmetric and asymmetric converter 5 丨. In addition, because the broadcast band requires a lower reference frequency, an external The oscillator 52 provides an output signal via a frequency divider 53 which can be adjusted by the digital signal processor D s P. All specific functions received by the broadcast, such as stereo detection and included in the broadcast signal Other functions such as RDS (radio data signal) are completely performed by the digital signal processor DSP or the baseband audio interface b A. For example, the AFC signal used to readjust the broadcast receiving frequency when the broadcast transmitter changes The baseband audio interface B a 丨 is generated and supplied to the second control input of the controllable oscillator 4 8 for adjusting the frequency of reading broadcast reception. The child band GSM and DCS 1800 are of course only examples, as long as they need to be reserved from time to time The present invention is equally applicable to other receiving frequency bands.
